Disclosure requirements of the Code

Under Rule 8.3(a) of the Code, any person who is interested in 1% or more of any class of relevant
securities of an offeree company or of any securities exchange offeror (being any offeror other than an
offeror in respect of which it has been announced that its offer is, or is likely to be, solely in cash) must
make an Opening Position Disclosure following the commencement of the offer period and, if later,
following the announcement in which any securities exchange offeror is first identified. An Opening
Position Disclosure must contain details of the person’s interests and short positions in, and rights to
subscribe for, any relevant securities of each of (i) the offeree company and (ii) any securities exchange
offeror(s). An Opening Position Disclosure by a person to whom Rule 8.3(a) applies must be made by
no later than 3.30 pm (London time) on the 10th business day following the commencement of the offer
period and, if appropriate, by no later than 3.30 pm (London time) on the 10th business day following
the announcement in which any securities exchange offeror is first identified. Relevant persons who
deal in the relevant securities of the offeree company or of a securities exchange offeror prior to the
deadline for making an Opening Position Disclosure must instead make a Dealing Disclosure.

Under Rule 8.3(b) of the Code, any person who is, or becomes, interested in 1% or more of any class
of relevant securities of the offeree company or of any securities exchange offeror must make a Dealing
Disclosure if the person deals in any relevant securities of the offeree company or of any securities
exchange offeror. A Dealing Disclosure must contain details of the dealing concerned and of the
person’s interests and short positions in, and rights to subscribe for, any relevant securities of each of
(i) the offeree company and (ii) any securities exchange offeror(s), save to the extent that these details
have previously been disclosed under Rule 8. A Dealing Disclosure by a person to whom Rule 8.3(b)
applies must be made by no later than 3.30 pm (London time) on the business day following the date
of the relevant dealing.
If two or more persons act together pursuant to an agreement or understanding, whether formal or
informal, to acquire or control an interest in relevant securities of an offeree company or a securities
exchange offeror, they will be deemed to be a single person for the purpose of Rule 8.3.

Opening Position Disclosures must also be made by the offeree company and by any offeror and
Dealing Disclosures must also be made by the offeree company, by any offeror and by any persons
acting in concert with any of them (see Rules 8.1, 8.2 and 8.4).

Details of the offeree and offeror companies in respect of whose relevant securities Opening Position
Disclosures and Dealing Disclosures must be made can be found in the Disclosure Table on the
Takeover Panel’s website at www.thetakeoverpanel.org.uk, including details of the number of relevant
securities in issue, when the offer period commenced and when any offeror was first identified. You
